| 英文摘要 | Spinel-type transition metal sulfides possess various super physical properties including colossal magnetoresistance (CMR). The research of the mechanism of the CMR effect is of great value for the development of the CMR sulfide materials, whereas the CMR effect of the spinel chrome-based sulfides is unclear up till now. The A(0.05)Co(0.95)Cr(2)S(4) (A=Zn, Ni, Cd, Fe) samples were prepared by solid-state reaction method. Their effects of magnetic and non-magnetic metal elements on crystal structure and magnetic properties of CoCr2S4 after doping were studied. XRD measurement shows that the doped A(0.05)Co(0.95)Cr(2)S(4) (A=Zn, Ni, Cd, Fe) samples exhibit pure spinel structure, in which their crystal cell parameters increase proportional to the ionic radius of the doping elements. Magnetoresistance measurement shows that all the samples exhibit giant magnetoresistance effect. Doping weakens the ferromagnetic interaction, which leads to the decrease of TC of A(0.05)Co(0.95)Cr(2)S(4) (A=Zn, Ni, Cd, Fe). In the low field of 0.01 T, the curves of the zero-field cooling (ZFC) and field cooling (FC) exhibit magnetic irreversible phenomena. All the samples exhibit typical ferrimagnetic hysteresis loops, among which Zn0.05Co0.95Cr2S4 shows the largest value of coercivity. |
